Thread: Class/Object Array?

Well all you do is this declare an array of objects like so

Code:

class Unit
{
public://needed to change to public so you can access them would 
be better to make accessor functions but i didn't want to take the time :)
float Id;
int TypeId;
int MaxHp;
int Hp;
int Range;
int Power;
int Move;
int Cost;
int Type;


//to create a new unit
void CreateUnit(int TypeId)

//to delete an old unit
void DeleteUnit(float Id)
};

int main(void)
{
  unit myClass[10];
  myClass[1].hp=myClass[1].hp-20;
  return 0;
}

Well I don't see why you would need to declare it inside of the class itself. As for increasing the array size I'm sure there is a way but ill leave that up to more expericanced people of that region than me(probably something in the STL). The way it looks though I would just make a maximum unit amount that you can have and then check if the player(user) has reached that maximum.

or, somebody besides me could show you how to use a vector

maybe i should learn some of this c++ garbage

As you have it currently defined, a unit object should consist of a single unit's attributes. A unit object should not internally collect together an array of units.

I would probably look at a wrapper class that consists of an STL container storing your multiple Unit members. This would be a better place to put your CreateUnit and DeleteUnit member functions as well.

Code:

//Stores information about a single Unit
class Unit
{
private:
float Id;
int TypeId;
int MaxHp;
int Hp;
int Range;
int Power;
int Move;
int Cost;
int Type;

public:
};

//Stores information about a collection of many Unit objects
class Units
{
private:
    vector<Unit> m_Units;

public:
//to create a new unit and stores it in the vector
void CreateUnit(int TypeId)

//to delete an old unit from the internal vector
void DeleteUnit(float Id)
};

A vector, or other suitable STL container, i.e. perhaps a deque or set, will be able to grow dynamically to suit your needs. The Units class would store all of your Unit objects and also have the public member functions to create and delete new Unit objects from this vector.
